A device for near-field and ultra-high-frequency communication, the device includes a near-field-communication antenna, an ultra-high-frequency antenna, a control unit including a controller for controlling the ultra-high-frequency antenna and a controller for controlling the near-field-communication antenna, a first carrier on which the NFC antenna is located, a second carrier on which the control unit is located, the first carrier and second carrier being located one above the other and connected by mechanical support pins, it is proposed that the ultra-high-frequency antenna be located on the first carrier and be connected to the control unit via: a first connection located on the first carrier, at least one pin made of conductive metal, and a second connection located on the second carrier, so as to produce a bidirectional ultra-high-frequency antenna.
Legal claims defining the scope of protection, as filed with the USPTO.
5. The device as claimed in claim 4, wherein the ultra-high-frequency antenna is integrated into the near-field-communication antenna and is connected on both sides to the near-field-communication antenna by the frequency-filtering means.
6. The device as claimed in claim 5, wherein the filtering means comprises an inductor and/or a capacitor.
7. The device as claimed in claim 1, wherein the near-field-communication antenna, and the ultra-high-frequency antenna are connected to the control unit by a common pin, and by a first and a second common via (v1′, v2′) and in that the device further comprises frequency-filtering means.
8. The device as claimed in claim 7, wherein the filtering means comprises an inductor and/or a capacitor.
9. The device as claimed in claim 7, wherein the ultra-high-frequency antenna is integrated into the near-field-communication antenna and is connected on both sides to the near-field-communication antenna by the frequency-filtering means.
10. The device as claimed in claim 1, wherein the first carrier and/or the second carrier consist of printed circuit boards.
11. A portable user apparatus comprising a communication device as claimed in claim 1.
12. An inductive charger for a portable user apparatus comprising a communication device as claimed in claim 1.
13. A motor vehicle comprising a communication device as claimed in claim 1.
